WebIn this work, based on the celebrated Griffith theory that interprets the energy release rate as the surface energy density, we have systematically investigated the fracture energy release rate in Peridynamics for a number of finite crack models: two-dimensional (2D) plane strain finite size horizontal crack, 2D edge crack in a half space, 2D … WebPeridynamics In continuum mechanics, the internal force is determined by the local deformation gradient and corresponding constitutive material model, while, in Peridynamics, it is replaced by an integral form with a set of non-local bond forces within a horizon. [Silling 2000] This makes Peridynamics very suitable in material failure analysis.
